Diaz shares 2½-year-old daughter Raddix with Madden, 43. She announced earlier this summer that she is coming out of retirement to make a movie with Jamie Foxx for Netflix after not starring in a film since 2014's Annie, which also starred Foxx.

The Bad Teacher actress spoke about aging in a conversation with Gwyneth Paltrow on GOOP's podcast in May, explaining her "whole concept of aging has just changed completely, even in the last 10 years," especially since becoming a mom.

"It's totally opened up. I'm excited. I've got 50 or 60 years to go — I want to live to be 110, since I've got a young child," she said at the time. "I think you have this amazing moment in your 40s where you appreciate who your parents are, and I want to have that moment with her — be there with her in her 40s."

Diaz said she's counting on her family's genetics to benefit her longevity: "My family's from sturdy stock. My grandmother was running around in the hot San Fernando Valley sun at 72, hauling big bags of rabbit feed and chicken feed around. I think I've got some of that. And, as is true for most people, I think how I look and feel is some combination of what I do and what I don't do."
